7x-7

x7-7

Answer 2

From the given question the correct answer is:

the simplification of 3(2x-4) + x² +5​ is x²+6x-7

Given:

3(2x-4) + x² +5​

To find:

3(2x-4) + x² +5​=?

Solution:

we have to simplify the expression

so,

first, we will open the bracket.

=3(2x-4) + x² +5​

=6x-12+ x²+5

=6x-7+x²

now arrange the equation in the form of ax²+bx+c

hence, the simplification of 3(2x-4) + x² +5​ is x²+6x-7
